Russell King 9eedd96301 ARM: DMA: Replace page_to_dma()/dma_to_page() with pfn_to_dma()/dma_to_pfn() ... Replace the page_to_dma() and dma_to_page() macros with their PFN equivalents. This allows us to map parts of memory which do not have a struct page allocated to them to bus addresses. This will be used internally by dma_alloc_coherent()/dma_alloc_writecombine(). Build tested on Versatile, OMAP1, IOP13xx and KS8695. Tested-by: Janusz Krzysztofik <jkrzyszt@tis.icnet.pl> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>		2011-01-03 11:27:43 +00:00
